Note: 1.Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2.The device is guaranteed to meet performance specification within 0℃ ~ +70℃ operating temperature
range and assured by design from -20℃ ~ +125℃.

Note 1: Guaranteed by design.
Note 2: Regulation is measured at constant junction temperature, using pulsed on time.
Note 3: Current limit is measured at constant junction temperature, using pulsed on time.
Note 4: Dropout is measured at constant junction temperature, using pulsed on time, and the criterion is VOUT inside
target value±2%.
Note 5: Dropout test is skipped at the condition of VIN<3V.
